The best film of 2021 was one few people even heard of: The Electrical Life of Louis Wain, directed by the Brit Will Sharpe. A fantastical biopic, it told the story of the English visual artist who popularized cats in the Victorian era through his surreal illustrations. Benedict Cumberbatch portrays the lead in his finest performance to date, and the sublime Claire Foy inhabits his wife, Emily. After tragedy strikes the couple, Wain’s fragile mental state leads to an increasingly psychedelic style and a nervous breakdown. Sharpe, all of 35, displays a dazzling visual palette, his own art matching that of his subject. After a brief, limited run in theaters, it was released on Amazon Prime with little fanfare. That’s a shame: The picture is a masterstroke.
